Question

A circus artist is climbing a 20 m long rope which is tightly stretched and tied from the top of a vertical pole to the ground. Find the height of the pole if the angle made by the rope with the ground level is 30degree ​

Answer 1

Answer:

Let AB be the vertical pole and CA be the rope. Then,

∠ACB=30  and AC=20 m

In right △ ABC,

since 30 = AB/AC

1/2= AB/20

AB=10 M

Height of Poles Is 10M.
